Change QuicConnection::cipher_id() to get underlying cipher id differently.

The current implementation doesn't work if cipher_id() is called outside of ProcessUdpPacket() stack. The new implementation iterate through all decrypters at different encryption levels to get the cipher id.

Also renamed --gfe2_reloadable_flag_quic_limit_new_streams_per_loop to --gfe2_reloadable_flag_quic_limit_new_streams_per_loop_2.

Protected by FLAGS_quic_reloadable_flag_quic_limit_new_streams_per_loop_2.

QUICHE stands for QUIC, Http, Etc. It is Google‘s production-ready implementation of QUIC, HTTP/2, HTTP/3, and related protocols and tools. It powers Google’s servers, Chromium, Envoy, and other projects. It is actively developed and maintained.

There are two public QUICHE repositories. Either one may be used by embedders, as they are automatically kept in sync:

To embed QUICHE in your project, platform APIs need to be implemented and build files need to be created. Note that it is on the QUICHE team's roadmap to include default implementation for all platform APIs and to open-source build files. In the meanwhile, take a look at open source embedders like Chromium and Envoy to get started:

QUICHE is only supported on little-endian platforms.
